GEORGE G. SOHROEDER, OF WASHINGTON, DISTRICT OF COLUMBIA, ASSIGNOR TO FARM MOTOR. COMPANY, A CORPORATION OF SOUTH DAKOTA.

MOTOR-VEECLE.

To all whom it may concern:

Be it known that I, GEoRsn G.. Someon- DER, a citizen of the United States, residing at Washington, in the District of Columbia, have invented new and useful Improvements in Motor Vehicles, of which the following is a specification.

This invention relates to certain new and useful improvements in motor vehicles.

The invention has for its object the pr0- duction of improved means for applying the motive power to .the traction wheels.

A further object is to provide simple and improved means for connecting and disconnecting the power with said traction wheels, and also for reversing the latter.

A further object is to provide improved means for steering the vehicle. i

A further object is to provide the traction wheels with means for obtaining a secure grip upon the surface of the roadway. And a further object is to provide means for regulating the position of the tractors and con- The invention will be hereinafter fully set forth and particularly pointed out in the In the accompany tion'. Fig.2, is a plan view thereof. Fig.

ferred' form, and 21. the en e or motor from which power is derived. counter shaft 22, is geared with the main power shaft 23, by

means of worm. gears 24, said power shaft 23, being provided with the usual momentum wheel 25. Means are provided, such as a clutch 26, operated by a rod; 27, whereby shaft 22, may be connected and disconnected with the power. The shaft 22, is mounted in bearings carried by casings A and B, forming part of a frame 28. Saidi casings serve to'protect suitable gearing by means ofwhich power is transmitted to the traction.

pinions meshing res ectively with pinions 31, 31 mounted on s ort shafts 32., support-- ed in casings A, B, below shaft 22, slmilar j 'pinions 33, 33 being secured to the op site ends of shafts 32. To the rear of shaft s22 and 32, in each casing, is supported a third shaft 34, pinions 35, 35 being mounted on one end. or each shaft 34, and meshin with the pinions 31, 31 res ectively. On-t e opposite end of each sha t 34, is mounted a pinion 36, 36 res ectively.

The ends oi' shaft 22, terminate'adjacent pinions 30, 30, short shafts 37, being mounted in adjacent bearings with their ends abutting against the adjoining ends of said shaft- 22. Pinions 38, 38- are respectively secured to the outer ends of each shaft 37, said ions meshing with toothed collars 39, carried by the traction wheels 29. Pinions 41, 41 are'slidably mounted on shafts 37, the

.sition of said pinions 41, 41' regulated by means of pivoted -arms 42,'4-2f connected by suitable rods-'43, to; operating levers 44, 44, said levers being provided withany Y preferred form of locking mechanism, The frame 28', is pivoted in anysuitable manner to 20, and the whole frame is s on' its pivot by means of 'a steering whee 45, engaging a sprocket chain 46, which in turn is connected at its ends to the opposite ends openings formed inthe rims-of wheels 29.

Ah'axle 50, is also mounted'o n eccentric 54,

for'shifting ring 51, said eccentricbeingipto tidied with a gear-55, for operating the same; Said ear is rotated by a pinion- 55' provided with veled teeth meshing with a beveled pinion 5'6, secured on one end of ashaft 57, mounted inan inclined bea sleeve'59t Said sleeve. is preferably provi ed with an 109/ enlargement 58, having teeth adapted to receive the angular end 60, of an eperating/ handle 6-1,- to lock the same from movement." Said-handle is pivoted'upon a disk 62, keyed to shaft5-7, and the angular end 60, is nor:- mally held in lockedposi-tion by a spring 63;. A reinforcing strip 65, is-formed on theinner side of the rim of each wheel, said strip'bein'g vided with tractor bocks 53,.which wor in provided with enlargements 66, surrounding the, openings in which the tractor blocks work. I

Theoperation of the parts is as follows 5 When it is desired to move forward, the shaft 22, is connected with the'power by means ofclutch 26 and the pinions 41, 41 are shifted to mesh with pinions 33, 33, respectively.

Shafts 32, will then be rotatedfby reason .of'

the. engagement of pinions 30, 30 and. 31, 31, said shafts imparting rotation to pinions 41, 41 bymeans oftpinions 33 33. Thus pinions 38, 38 are rotated and the. ower'ap plied to the wheels. .(See Fig.4.)

5 desired to reverse the vehicle, the 'pinions .41,

A1 are shifted to the position illustrated in- Fig. 5. In this position the shafts 34, are.

. reversely rotated through the medium of pinions 35, 35, meshingwith pini0ns 33, 33,

respectively, the reverse rotation being imarted to pinions 41, 41 ,byreason of the atter having been thrown into mesh with the pinions 36, 36,flrespectively. When it is intended to turn the vehicle the frame 28,} is swung around and the wheel on the inside of the turn' is reversely rotated. For in-' stance, in Fig. '6, themechanism adjacent casing A is connected u to impel the adjoining wheel forward, w is the mechanism in casing B is shifted to reverse the adjoining -wheel,- the parts being shown in the act ofmaking a turn to the left. When it is desired to tem orarily disconnect the traction wheels from-t epower, theinions 41 41 are shift 13.5 ed;t0 .the positions own. in higi7, where they. are .dlsengaged from all of the driving pinions. Under normal conditions the co: centric 54, is secured in position illustrated in .Fi 8. When the parts are in this posi- 0" tion t e tractors 53, are forced out of the top of the rim 8, in at the bottom, or at the point contacting with the round. Thus that portion. of each wheel t at engages the ground resents. an approximately smooth surface.

f, however, there is a heavy load, a sandy or muddy road, ora steep grade, or any other condition which tends to causesli ping of the wheels, the eccentric is shifted position illustrated in Fig. 10. When in this position the eccentric forces the tractor locks downward to-the limit of their move, ment, thus providing gripping devices which engage the surfaceof the ground to prevent by the vehicle may be impelled forward or fve 'cle: Another'advant 'nesswith which the traction wheels can be temporarily disconnected from the Vhen it is to the a reverse direction. It will be further noted that I have rovided means whereby the tractionwhee may be positively rotated in op osite directions-in the steerin of the eliesint ereadi ower. It w11l also be observed that by providmg'the Wheels with tractors, and means for adplsting the latter, I am enabled to vary the traction power of the vehicle to suit practically all conditions.
